Check Digit Verification of cas no

The CAS Registry Mumber 94814-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,1 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 94814-88:
(7*9)+(6*4)+(5*8)+(4*1)+(3*4)+(2*8)+(1*8)=167
167 % 10 = 7
So 94814-88-7 is a valid CAS Registry Number.

Cyanic Acid Ester. 35. On Formation and Consecutive Reactions of N-Cyanato Phthalimide. New Specifically Activated and Blocked Isatoic Acid Derivatives

Martin, Dieter,Nadolski, Karin,Gruendemann, Egon

, p. 737 - 746 (2007/10/02)

Depending on the reaction conditions N-hydroxy-phthalimide affords on treatment with cyanogen bromide via N-cyanato phthalimide 2 the iminocarbonate 3 and isatoic acid derivatives 7 and 16.Both the latter react with nucleophiles as isatoic acid derivatives activated on the carboxylic group and protected on the carbamic group or vice versa, furnishing N,N-bis alkoxycarbonyl anthranilic acid amides 9, N-alkoxycarbonyl anthranilic acid 12, o-alkoxycarbonyl phenyl ureas 17 and the benzotriazepin-2,5-dione 14.The structures of the new compounds are proved by 1H-n.m.r. and 13C-n.m.r. measurements as well as independent synthesis.
